So... we have all of these formulas for calculating various things in the game, as well as the data to go along with it, but how much of it is 100% accurate? The data is fairly easy to confirm, as most people don't have a hard time finding patterns in the ROM data and extracting it from there, but the formulas are another story. How may people do you know who have decent knowledge of assembly and can find what they're looking for in the disassembly of the ROM? I sure haven't been able to find many... well, in fact, only one (Meowth346), and he claims to not remember how. [Roll Eyes]

Anyway, I wanted to see if anyone on here is interested in doing the necessary research to learn how to find these formulas themselves. I've already made significant progress in being able to read assembly, but I'm still incapable of finding these formulas for verification.

I guess it's somewhat of a hobby as well. I love to research things and learn. These formulas may all very well be 100% accurate already, but where's the fun in believing that when you could find out for certain yourself? [Smile]

So... if you already have any experience with assembly, or are interested in learning, let me know.

Well, in the past many things like the Red/Blue/Gold/Silver grand Battle Damage Formula were in fact read by people from the ROM's gameboy assembly code. I think this was the main thing that took many years to discover...as experimental testing of the previous Damage Formula had shown tiny errors in what it predicted (I should know, I was the one who was pointing these errors out, unfortunately I was never smart enough to be able to come up with the true Battle Damage Formula using only experimental data). Most of the other formulas the game uses are simpler and experimentation is enough to determine exactly how they work.

It's true though that some things have changed since Red/Blue/Gold/Silver days..the new Damage Formula is slightly different, other new formulas probably changed, etc...but I dunno if at this point trying to read ROM code is worth it for anything.

Maybe it wouldn't be worth the time just to find a few fixes or whatever, but it's still something I enjoy doing. I guess I'm just trying to find out if there are any other people who also like to do it. It would be nice to have someone I could discuss things with and to solve problems with. :P

Seems interesting enough and I'd find the information useful as well so~ I'll help out if I can~ I have some various formulas but I'm not entirely sure of their accuracy. Also, I don't believe Meowth346 EVER claimed to have the source code for Pokemon.

Do you have any experience with assembly? That's basically what it's going to take to obtain the formulas. Someone who can read it and knows where to look within the disassembly code of the ROM. However, if you're good at figuring out what a value is for (such as a seemingly random address in the memory), that would be useful as well.

That's not what I meant. He said he obtained the formulas for R/S from the disassembly of the ROM.
